Dab tsi yog hom hlau thiab hlau yog tsim rau qib 12.9 hex socket screws

Qib 12.9 bolts thiab screws xa mus rau ultra siab zog screws ua los ntawm 35CrMo, 42CrMo, thiab B7 alloy steel cov ntaub ntawv, nrog ib tug tsawg kawg nkaus tensile zog ntawm 1220Mpa thiab ib tug hardness ntawm 39-44HRC. Nws yog tsuas yog siv nyob rau hauv textile, hydraulic, txhaj molding, thiab machinery industries domestically.

1. Lub 12.9 qib ntsia hlau hais txog lub zog siab ultra-siab ua los ntawm SCM435 alloy steel cov khoom, nrog lub zog tensile yam tsawg kawg nkaus ntawm 1220Mpa thiab hardness ntawm 39-44HRC. Nws yog tsuas yog siv nyob rau hauv textile, hydraulic, txhaj molding, thiab machinery industries domestically.

2. Raws li cov khoom, nws tuaj yeem muab faib ua ntau hom xws li12.9 qib sab nraud hexagonal bolts, 12,9 qibInternal hexagonal taub hau screws(khob taub hau), 10.9 qib countersunk taub hau sab hauv hexagonal screws (pav ca), 10.9 qib semi round taub hau internal hexagonal screws (round khob), 12.9 qib set screws (machine meter), 12.9 qib internal hexagonal plug screws, thiab lwm yam. cov xov, nws muab faib ua ntxhib xov, xov zoo, metric, British, American, thiab lwm yam.

3. Qib 12.9 yog qhov ntau yam ntawm cov ntsia hlau, nrog rau siab hardness thiab tensile lub zog. Nws Rockwell hardness (HRC) tuaj yeem ncav cuag 39-44, thiab nws lub zog tensile tuaj yeem ncav cuag 1220N / mm2. Txawm li cas los xij, vim muaj cov duab sib txawv ntawm cov ntsia hlau tsim, countersunk hex screws (pav ca) thiab ib nrab ntawm lub taub hau hex screws (cov khob puag ncig) ua los ntawm tib cov khoom tuaj yeem ua tiav qhov tsawg kawg nkaus tensile zog ntawm qib 10.9. Nws tuaj yeem ua tau raws li qhov xav tau siab ntawm kev lag luam thiab kev lag luam mining rau fasteners nyob rau hauv tshwj xeeb zaus thiab cov khoom.

Ningbo Zhongli bolts manufacturing Co., Ltd tsuas yog muab cov qib tiag tiag 12.9Hex qhov (socket) Screws DIN912, ISO4762, lub Hoobkas muaj 21 xyoo kev tsim khoom.
